Chemical engineering . tion filed AprilII. invention relates to an arrangement of electrodes whichpermits the use of very large tanks, its object being to reduceeither the size or the cost of an electrolytic metal depositingplant, or both : particularly of an electrolytic refinery. Thedepositing plant is more in the nature of a flooded floor, onwhich the operations are carried out, than the usual largenumber of individual tanks, the elimination of a large number of tank sides and ends and the intervening spaces, varying incost of construction and in space. The invention is stated tobe of special advantage in an electrolytic lead refinery, as ametallic lining, which prevents leaks, is expensive, and othermethods of making tight tanks require thick sides and bot-toms. One arrangement of the electrodes is shown in Fig. tank I of any desired length, with the middle part removed,contains the electrolytic solution from which metal is depositedon the anodes 2 and cathodes 3. The current enters through. ^3 .?? 2 FIG. 3.—ELECTRODE .\RRAXCEMENT FOR ELECTROLYTIC PL.\.NT. the positive bus-bar 4. passes to the anodes connected to it,flows through the solution to the cathodes and thence to tlieconductor 5. From there it goes to the next series of anodes,and continues passing in that manner through the whole solu-tion, until it leaves the tank by the negative bus-bar 6. It isstated that by leaving a double space between the anode of oneblock of electrodes in multiple and the cathode of the nextblock of electrodes in multiple, and so doubling the local re-sistance, there is obtained an equal flow of electric currentfrom both sides of all electrodes, with the exception of ananode at one end and a cathode on the other. Process of Eleclrolytically Refining Copper Alloys. A. Troy, N. Y. Patent 789,523, May 9, 1905. Applica-tion filed April 11, first step of the process consists in eleclrolytically dis-solving the copper-nickel alloy, by using it as anod
